daemon: add diagnostics logging + guard VNI control key consumption behind engine.is_enabled()

Browse source 
- Add 'Event loop started' log at beginning of run_with_evdev
- Add reason for non-interrupted fetch_events errors
- Log each injected key with engine state, character, buffer length, and commands
- Fix VNI control digits being silently consumed when engine is disabled
